UNITED. sTAr s OSCAR WOODWARD, OF MONTCLAIR,

NEW JERSEY,- AssIeNo BY MESNE Assume MENTS, TO REMINGTON TYPEWRITERCOMPANY, OF ILION, NEW YORK, A CORPO- RA TION OF NEW YORK.

To all whom it may concern Be it known that I, Oscar; \VOQDWARI),citizen of the United States, and resident of Montclair, in the countyof Essex and State of New Jersey, have invented certain new and usefulImprovements in Type-'Writing Machines, of which the following is aspecification.

My invention relates to supporting feet for-writing machines andtheprincipal object of said invention is to provide improved devices ofthe character specified.

To the above and other ends my inven-' tion consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter describedand particularly pointed out in the claim.

In the.accompanying drawings, Figure 1 is a fragmentary sideel'evation',:partly in section, showing part of the machine frame andone'of the supporting feet attached thereto, the view showing theinner-side of the forward left-hand portion of the base tional-view',taken on a plane represented by the line m;'c of Fig. 1 and lookmgjm thedirection of the arrows at sa1d,.lme.

showing a modified construction.

Referring first to Figs. 1 to 5' of the draw-.

ings, 1 indicates the base frame of a typewriting machine, such, forexample, as the No. 10 Remington typewriter. The side of the base isformed with a vertical semi-circular groove or depression 2. As shown inFig. 2 the lower end of the groove is flared or tapered, as indicated at3, to provide a socket portion. Secured to the side of the base as byrivets 4 is a foot bracket 5 of ing the groove 2 and being rounded orcurved as indicated at 6, thus providing together with the lower flaringportion 3 of the groove 2 a foot receiving socket, the socket portion 6complementing the socket TYPE-WRITING MACHINE.

portion 3. As is clear from F the .portion 6 is pressed or otherwiseformed with corrugations to provide a series of grooves or depress ons 7on the inner face.

My new. and improved supporting foot.

comprises a foot proper 8 of rubber or rubber composition or othersuitable resilient -and. expansiblematerial, said foot consisting of acylindrical base portion 9 audit tapered neck or socket-engaging portion10,"

said 'neckflbeing'adapted to fit readily into the socket 3, 6 in: themachine frame. The foot proper isfOrmed with'ap vertical hole or bore11, and the lower end of the bore '11 is enlarged or counterbored at vThe bore [11 receives a lining in the form of 'a metal halvesor-portions 14, as shown in Figs. 2, 3 and The diameter of the sleeve issuch sleeve enmay readilybe slipped into the bore. The

but is of greater diameter than the sleeve, so that said head engages.directly with the lower end of the sleeve. The body of the screw is ofsuch diameter that it passes freely through the sleeve but has no sideplay therein, the sleeve serving to center the screw and maintain thehead thereof in en 'gagement with the lowerendof said sleeve.

The upper'end' portion of the screw '16 is reduced in diameter andthreaded to coopcrate with the conical nut 17, which when screwed down,seats itself in the bevel 15 at the upper end of said sleeve. The outersurface of 'the nut is knurled, corrugated or roughened, as shown at17*, Fig. 4, so that the corrugations or knurls act as projectionsprovided with a head 18 which is adapted to pass freely through thecounterbore 12 75 tube orsleeve 13 which may comprisetwo.

which it will catch on the corners of the sec-- ticnal sleeve or splittube 13, thus preventing the nut from rotating when the screw 16vdriver;

of the is rotated by a screw Prior to the insertion foot in the machinethe screw 16 and nut 17 soloosely engage the sleeve or tube l3'that thelatter the tube 13 and the expanding devices 16.

the

and 17 may be readily, arranged in place,

- tapered neck or-socket portion being forcing the halves or Fig. 2wherein Q outward or radially;

more evenly j the outward easily inserted from the bottom upward in theflaringisocket 3, 6. Thereafter the screw 16 is rotated by a screwdriver, the rotation of the screw operating to draw. down theconical'nut into'the sleeve or tube, parts of the sleeve apartfat theirupper ends as illustrated in the sleeve sections are shown from thebottom upward, thus diverging 1 causing \l-shaped openings or spaces14"" between the sleeve sections." The relative movement of the sleeveparts operates in turn to expand the rubber,'forcing it outwardandcausing it to press'tightly against the inner walls of the footsocket; and also to fill the depressions 7,1thu's rendering'moredifficult the accidental removal or displace 'mentof the foot. Thus itwill be notedthat the head of'the bolt or screw bears at'one end of'thesleeve and the nut at the opposite end, and when the bolt is turned, thehead and-nut act compressively endwise on the sleeve and at the sametime the upper part of the sleeveis expanded to force the rubberlaterally so as socket. It will be observed that the screw and nut,instead of co-acting directly with the rubber foot proper, co'dperateinstead indirectly therewith through the interposing the sleeve betweenthe expansi ble foot and the expanding devices the expansive force ofthe latter is transmitted sleeve this force would in large measure betransmitted upward and downward axially of the screw and would tend to-com-.

press the rubber in an up and down direction rather than expand itoutwardly. Furthermore, the sleeve operates to transmit pressure orexpansive force tothe neck 10 than would be the caseif the expandingdevices operated directly on the foot proper.

The foot as an entirety may be removed b turning, the screw backward,which ordi narily will cause its head to move downward away from thetube or sleeve without forcing the conical nut upward. After the screwhas been given a few left-hand turns it may be pushed in until its headrests against the lower end of the sleeve 6, forcing the expanding nutout of the tube and to interlock with the sleeve 13. By

whereas. without the permitting the foot to contract so that it may beeasily foot socket. Various departing from v the scope of my invention.

For example, the expansible sleeve or tube, instead of being made intwo-independent drawn downward out of the changes may be- ,made withoutfrom the top at a number 21. 7 Fig. 7"shows a one-piece tubeor sleeve'22 which as indicated at 23',-is split throughout its entirelength;while Fig. 8 shows a .sleeve 24' composed of three sections '25. I

In Fig. 9.; is illustrated a modified construction' of receptacle orsocket for the foot.

In the Fig. 9 construction the 'bracketlfi of the Fig.1 form is replacedby a bracket which instead of a wide,

or bridging portion'6 has a narrower, plain, strap-'likebridging portion26. This" strap portionis slightly inclined toward the tapered socketportion 3 on the f-ramefproper, thus providing a plain of less heightthan the corresponding socket of the first described constructionl Thesupporting foot as a whole comprising the foot-proper 8, the sleevesections 14, the screw 16 and the nut 17 may be introduced into thesocket 3, 26 from the bottom upward as before, but in this case theupper end of the-neck: 10' will project abovethe top of thejsocketportion 26. The consev quence will be that when the screw and nut arecontracted by drawing down the nut to expand the neck, the portionthereof contiguous to the ,strap 26 will be. forced or pressed outwardvery tightly against said. strap while the part of the neck above thestrap will bulge over the top of the strap as indicated at 10*. It willbe apparent that the-bulge will edectually lock the foot in place and,will prevent accidental withdrawalthereof from its socket or receptacle.

-Other changes in constructionwill readily suggest themselves to thoseskilled in the art. I

It will be understood that while have shown and described one supportingfoot the machine is provided with a plurality of these feet, four beingthe number ordinarily employed.

It will be seen that I provide a foot which may be readily inserted inplace in the machine and" as readily removed therefrom; that said foot,after it has been arranged in place,"may be expanded so as practicallycorrugated curved tapered socket 3, 26

to prevent accidental removal or displace ment; that removal isprevented both by the abnormal friction between the foot and its socketand also by the locking action exerted in the Fig. 1 construction by therubber Such which fills'the depressions 7 and in the Fig.

construction by the bulge or overlapping portion 10*; and that in bothinstances what may be termed-the locking portions of the foot areexpanded or pressed outward radially beyond the interior wall of thesocket. prevention has been a result long I sought, the dropping out oraccidental pullmg or forcing out of the rubber foot being 10' ofdifferent diameters, the bottom heretoforeone of the commonest and mostannoying defects in typewriting machines. y improved. foot, it will beobserved, is
